this line is also very curious under my theory, because it’d make sense if sans knows this world will be destroyed because he’s seen it happen before in deltarune first hand.

he doesn’t want to lose it all again and have this world forever destroyed.

that’s why i think sans says “i know your type” when describing the player’s completionist instincts.

he’s talking about gaster, a morbidly curious scientist experimenting with worlds because he think he can derive a new outcome from it.

now this is a bit of a shot in the dark but i think the two ppl trying to fix the machine are gaster and the player and the “machine” is the DEVICE layer gaster uses to connect to the player.

it might even be the same one we see in sans’ lab

it makes me wonder, if what i’m saying is right and we’re heading towards reaching the ‘absolute’ of deltarune i think we will reach the same fate. the world will be destroyed irreparably, it also makes me think about this tweet

and once you’ve done everything, the world is destroyed, because there’s no point in keeping it around anymore when every possibility has been explored.

you can still replay the game of course but that experience is just left hollow and in the words of andrew cunningham:

then i realised that’s why we have 3 save slots.

gaster literally says “PREPARATIONS ARE COMPLETE” when overwriting the ur file to all 3 save slots. he’s planning for you to replay them. to find every secret in order to create the “new future” he so desperately wants.
